对水力机械和水力喷沙割缝方法进行了对比分析。结果表明 ,这两种方法均适用于强化采油。前一种工艺在矿场实施后平均采油量增加了 5～10倍 ,后一种工艺在低产井中应用后使产量增加了10倍。水力机械割缝射孔所要求的设备和材料要少些 ,而技术条件要求要多得多
Hydraulic machinery and hydraulic sandblasting methods were compared. The results show that both methods are suitable for enhanced oil recovery. In the former process, the average oil recovery increased 5 to 10 times after implementation in the mine, and the latter process increased the production by 10 times after the application in the low production well. Hydraulic machinery kerf perforation required less equipment and materials, and technical conditions require much more
